This digital concrete test hammer, entirely designed and manufactured by Matest with advanced technology, is capable of assessing concrete strength and detecting potential structural issues early on. This capability enables the planning of preventive maintenance interventions before more severe damage occurs. By identifying areas in need of maintenance, it helps avoid the necessity of carrying out repairs across the entire structure. Additionally, conducting targeted preventive maintenance interventions reduces the amount of waste generated from demolitions and reconstructions. The unit comprises the standard mechanical model C380, enhanced with an electronic transducer that measures rebound values and automatically provides results on a graphic display. During test performing: Shows index value Shows average index value Allows to select measuring system in N/mm2 (MPa) or Psi Shows the number of performed rebounds Shows date and time Identifies tested element Identifies automatically and shows rebound angle Shows battery life NOTE: The digital Matest test hammer can be connected to the Ultrasonic Tester high-performance mod.
